osquery

Simply put, it turns your computer system into a database. Instead of memorizing complex system commands, you can query running programs, network ports, or file info using standard SQL.

Solves the pain point of needing different commands for different systems. Previously, you used netstat for ports and ps for processes; now it's unified SQL, consistent across platforms, and allows batch analysis.

1. System Administrators (Ops)

2. Security Auditors

3. Developers needing server monitoring

4. Tech enthusiasts curious about system internals

1. Quickly find who is using a specific network port

2. Scan for suspicious hidden processes

3. List all installed software

4. Check login logs for anomalies

1. If you know SQL, you can use this, low learning curve

2. Supports Linux, Windows, and macOS

3. Fast response, suitable for large-scale monitoring

4. Active community with many ready-made tables

Requires basic SQL knowledge. Needs to be installed as a daemon on the server or locally. Might be heavy for occasional personal use, better suited for enterprise deployment.
